My German bubble is also maybe half Whatsapp and half Signal. Many contacts have both.
It looks the same, feels the same and does the same. Notifications appear in exactly the same place, regardless of the messenger.
I don't understand why people are so passionate about not using the supposedly more private service next to the trivially less private one.
I also don't think adding messengers is such a big deal in non-technical circles, given the need is there. They just install it and its done.
An example: One of my younger generation family chat groups moved from Facebook Messenger to Signal because Messenger started blocking links to some streaming services in 2018. - No blocked links since.
